AÂ wheelchair structure comprises: a wheelchair frame 51, an auxiliary drive device such as a motor 61 and a combined frame A; the combined frame comprises an assembly base frame (10, figure 3), a moveable rack assembly (20, figure 3) and a resilient support (30, figure 5). The assembly base frame comprises a horizontal protrusion (110, figure 3) attachable to a receiving portion 512 on the wheelchair frame, and a sleeve portion 12. An extending portion 21 of the movable rack assembly is inserted into the sleeve portion and a limiter (23, figure 5) is used to prevent the moveable rack assembly from disengagement. A limiting portion 22 of the movable rack assembly is attachable to another receiving portion 510 on the wheelchair frame. The simple and efficient structure allows for rapid assembly and ease-ofÂ-operation. |
